There are 3 genetic types of FHH based on chromosome location. FHH type 1 accounts for 65% of cases and is due to inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR). Loss of CaSR function results in a reduction in the sensitivity of parathyroid and renal cells to calcium levels so hypercalcemia is perceived as normal. The other 35% have either a mutation GNA11 (19p13.3) seen in FHH type 2 or AP2S1 (19q13.2-q13.3) seen in FHH type 3 (see these terms) or in genes not yet discovered. FHH is rarely caused by auto-antibodies against CaSR in those without a mutation.
Mitral Valve Prolapse and Mitral Regurgitation. Review of mitral valve anatomy and function, including papillary muscle structure and function, with severe mitral valve prolapse and mitral regurgitation due to a flail segment caused by ruptured papillary muscle and chorda tendinae attachment.
An antecedent upper respiratory infection is present in 50% of patients. Abdominal pain is a presenting symptom in 1 0-15% of patients. The skin lesions are symmetric, involve dependent parts of the body, and classically progress from an erythematous, macular rash to papular purpura. The joints and kidneys are also commonly involved
A nephron (from Greek νεφρός (nephros) meaning "kidney") is the basic structural and functional unit of the kidney. Its chief function is to regulate the concentration of water and soluble substances like sodium salts by filtering the blood, reabsorbing what is needed and excreting the rest as urine.
Uterine fibroid embolization (UFE), also known as uterine artery embolization, is a minimally invasive procedure that is performed by an Interventional Radiologist (IR), a doctor who uses advanced imaging technology to see inside the body without surgery. UFE is often performed as an outpatient service and offers a much shorter recovery time than surgery. For more information on uterine fibroids and all your treatment options, including UFE,
The cause of pectus excavatum is not known however it can run in families, with up to 25 percent of affected patients reporting chest wall abnormalities in other family members. Pectus excavatum occurs in approximately 1 out of 400–1000 children and is three to five times more common in males than females.
Are you a first time would be mom? If yes, then you must be very excited to feel the first movement and kick from your baby. It is undoubtedly the most exciting experience for many expecting moms. It is an indication that there is a little angel growing inside you. There are interesting facts about baby kicks during pregnancy that you need to know.
This medication is used to treat certain types of serious (possibly fatal) irregular heartbeat (such as persistent ventricular fibrillation/tachycardia). It is used to restore normal heart rhythm and maintain a regular, steady heartbeat. Amiodarone is known as an anti-arrhythmic drug. It works by blocking certain electrical signals in the heart that can cause an irregular heartbeat.

The goal of surgical clipping is to isolate an aneurysm from the normal circulation without blocking off any small perforating arteries nearby. Under general anesthesia, an opening is made in the skull, called a craniotomy. The brain is gently retracted to locate the aneurysm. A small clip is placed across the base, or neck, of the aneurysm to block the normal blood flow from entering. The clip works like a tiny coil-spring clothespin, in which the blades of the clip remain tightly closed until pressure is applied to open the blades. Clips are made of titanium and remain on the artery permanently.
Most retinal tears need to be treated by sealing the retina to the back wall of the eye with laser surgery or cryotherapy (a freezing treatment). Both of these procedures create a scar that helps seal the retina to the back of the eye. This prevents fluid from traveling through the tear and under the retina, which usually prevents the retina from detaching. These treatments cause little or no discomfort and may be performed in your ophthalmologist’s office. With laser surgery, your ophthalmologist uses a laser to make small burns around the retinal tear. The scarring that results seals the retina to the underlying tissue, helping to prevent a retinal detachment.
Bariatric surgical procedures cause weight loss by restricting the amount of food the stomach can hold, causing malabsorption of nutrients, or by a combination of both gastric restriction and malabsorption. Bariatric procedures also often cause hormonal changes. Most weight loss surgeries today are performed using minimally invasive techniques (laparoscopic surgery). The most common bariatric surgery procedures are gastric bypass, sleeve gastrectomy, adjustable gastric band, and biliopancreatic diversion with duodenal switch. Each surgery has its own advantages and disadvantages.
Closure of a loop ileostomy is a relatively simple procedure although many studies have demonstrated high morbidity rates following it. Methods to reduce the number of complications, such as timing of closure or different surgical closure techniques, are investigated. The aim of this study was to evaluate the experience of the Abdominal Surgery Center at Vilnius University Hospital (VUH) ‘Santariskiu klinikos’ to review the complications after closure of loop ileostomy and to identify potential risk factors for postoperative complications.
